For best results, use a ripe, bubbly starter that has at least doubled after feeding, as a sluggish starter will slow fermentation and flatten your loaf. Adjust water slightly based on your flour; whole wheat absorbs more, so if the dough feels very stiff, add a teaspoon or two of water, and if it feels like thick batter, dust lightly with flour during folds rather than at mixing. Room temperature strongly affects timing, so rely on visual cues such as volume increase and bubbles rather than the clock. A long cold proof in the refrigerator deepens flavor and makes scoring easier, and baking the dough straight from the fridge helps it hold its shape. Always let the loaf cool fully to set the crumb; cutting too early releases steam, making slices gummy and harder to cut cleanly.
